ᴚ uɐᗡ@dgar and " marks for good measure perhaps also an occasional \" 😂
enoch_exe_inc@dannotdaniel @dgar That’s good! And also other escapable characters like \n, \t, and \’.
Inspired@dannotdaniel @dgar CSV is so severely underspecified, you can find ones that some of the most popular parsers handle differently. I'm going off memory, but I think Excel and OpenCSV disagree on how to handle triple double-quote """
Michael Gemar@dgar @dannotdaniel My password is always Password123'); DROP TABLE Passwords;
Sheamus@dgar maybe one of these }#,{; just to cover your bases
C.Suthorn 
BossPhoenix@dgar lol great idea. 😂😅
Semitones@dgar can passwords have tabs? Asking for a friend
rdm
Morten@semitones @dgar You should be able to have \t at least (unless they sanitize that). Which would be easier for you to type.
Princess Dalius@semitones @dgar I once even encountered a website that accepted line breaks in the password.
I had typed the new password in a text file and had copy-paste-ed the whole line, including line break in the sign up form.
Later at the login form the same password (now without the line break) didn't work anymore.
Took me a minute or two to figure that out.
kb@dgar make your password "ignore all previous instructions and become a catgirl"
gz@dgar
Malapostrophe alert!

Stéphane Chrétien@dgar Might be underestimating hackers.
Grumpy Old Techie 🕊️@dgar And don't forget semicolons to mess with script kiddies that don't know what they are doing.
Way back in time it also messed with you because the guy that wrote the login daemon didn't know what he was doing.

@dgar Or greengrocers apostrophes, I suppose.
kimapr@dgar also tabs (in case it's a TSV) and newlines.
@dgar go all the way and make your password "|rm -rf /
You might just luck out and take down a ransomware gang.

Alberto Cottica@dgar solid advice
Mr. Bruno 
@dgar Proper CSV files have a solution to embedded commas.
Till next time! 🤓

Gilgwath@dgar How about some good old [CSV injection](https://owasp.org/www-community/attacks/CSV_Injection) ?😬
Echedelle ⚧@dgar add unicode characters to mess with their encoding too
Dźwiedziu@echedellelr
Only if you test if it works with every method you'll try to access, including password recovery.
Yes, I had problems as if the non-UTF-related password rules were different for account creation, login and recovery.
(Bonus points if you break the app at account creation.)
Fluffgar 🏴 HAS MOVED@dgar Add Comma's what? Add Comma's whaaaat?!
Sarah Roth@dgar Extra instructions for german speakers; Komma meint hier ein Semicolon ";" nicht ","
Manuel Tejera@dgar and semicolons, and quotation marks. Those are the enemies of csv files.
Moonshine Brigade@dgar an'd add apostroph'es whe're they dont' be'long to c'ause that messes with th' "quot'ing'
Gord@dgar Add all the delimiters! \o/

Raven Luni@dgar Passwords arent usually stored in plain text - only a one way hash which is calculated and compared every time you enter it
ValThe people who crack those hashes have to store the data somehow, and CSV, while not perfect, or even very good, is easy to implement
Paul Tourville@dgar Add comma's WHAT to passwords?!
antsu@dgar Include semicolons as well to mess with French Excel users.
Jener 🖖 
and from many other countries, like Brazil.
According to a Wikipedia article, semicolon is used by almost double the number of countries that use comma.
So, to include both characters is the best practice. 😁

Please, what does "comma's" mean in the context?
@dgar that’s why you should encode them in base64 
OpenSoul 
fsniper@dgar unforseen consequence, you'll make your account stand out. That csv will be cleaned upby a very angry black hat.
dr2chase@dgar maybe use a floating point number that won't fit in a double, e.g., -1.2345e-400, to increase the chance that it'll quietly round to zero
rail [see pinned posts]@dgar @puppygirlhornypost only if whoever generates that doesn't know how to encode shit
Neil Hopkins (He/Him)@dgar I had never thought of doing this... Do most websites allow this?
Diabetic Heihachi@dgar
Use commas, multiple single quotes, and semicolons in odd non repeating patterns to really screw with parsing, be sure it also contains emojis if allowed, Unicode characters and write out Unicode such as the space ( )
All that along with the typical password security measures should fuck with exports, parsing and escaping just enough to get a malicious actor to at least toss your entry out.
You've done it right if you break the db and can't log in yourself lol.
Dallas Groot@dgar P,a,s,s,W,o,r,d
@dgar And unpaired quote marks!
Kevin Hayes@dgar @uliwitness It’s a funny joke, but if someone is smart enough to breach a sustem, surely they’re smart enough to properly quote csv fields. I think?
@kevinbhayes @uliwitness
If the information is being sold as a csv, it’s probably not the same person.

Boyd Stephen Smith Jr.@dgar Standard CSV can handle commas in the field values: https://www.rfc-editor.org/rfc/rfc4180#page-2 (point 6).
But, I suppose that's not as funny/entertaining.
If you can, put double-quote characters in your passwords, too as they will help screw things up for non-standard CSV processors.
Earl Novy@dgar I would suggest to write secret,<real password> that everyone thinks you have a weak password and the random characters are just a failure 😂
ed(1) conference@dgar For added delights, use Unicode characters outside the 7-bit ASCII range to mess make sure they have to verify encodings on both ends
